Review: Works great, a few minutes effort worth huge savings - This is great! Fit it to a 1988 Ford Ranger (it's universal). If you suspect your original inertia switch is faulty, you can unplug it and run a wire between the terminals. Then try to start it. If that works, it's the switch which needs replaced (compared to to expensive fuel pumps). Now, the OEM switch is $100+, and I was hesitant to try this one here that requires "rewiring" but this is easy and worth the significant savings. It took me a minute to understand the instructions in reviews, but once done, great. I'll try to clarify the instructions here: The change required is to move the placement of a wire on the wiring harness. The wire in the middle needs to be on the end (on the "C" and "NC" spots, see the switch itself for which those are). I was able to use a flat screwdriver to pry up the yellow plate, and a small flat screwdriver inserted into the top (at the end of the wires) to release the wire. Then just moved it one spot over. Other reviews didn't mention how to know which of the 2 wires on my vehicle go into which side of this switch...but wait, it doesn't matter. This is just an interrupter switch that closes the connection if the switch is shaken (e.g. if the car is rolled over or in an accident.) This is how this switch is universal. This kit comes with two connectors, so you'll only need to cut the wires before your old wiring harness, and clamp the included clips over your wires. I included a picture that shows this installed (before mounting, which is important that it's mounted securely). This switch works great and for 15 minutes more effort (VS. the one designed for your car that plugs right in) it's absolutely worth it, and a great buy!
Review: Pinned Wrong - The switch is wired to be normally open and not normally closed. The circuit is only closed when it is activated which is the opposite of what you want for power to a fuel pump. Repinning it is difficult. Also, the weather seals were not pushed in all the way and I had to seat them correctly.

## Questions & Answers

**Q: Will this fit a 1990 ford ranger 2.9 v6**
A: Fitment is not the issue.  You can find a place where it will fit.  Most likely it will physically fit in the same place the original one came out of.  What you want to know is will it work.  The answer is yes .  It doesn't care what car or truck it is in as long as you remain in the Earth's gravitational field and under the speed of light.

**Q: Has anyone had issues with the switch tripping during routine driving?**
A: No, I race my car, it has a stiff suspension and I drive on the street quite a bit. No problems at all

**Q: Will this fit a 1987 Ford ranger**
A: It will fit any car that you can identify the wiring for the fuel pump. It can be installed horizontally or vertically. I have mine at a diagonal facing forward so hopefully it will trigger from side impact as well.

**Q: Will this switch fit a 2005 Kia Sorento?**
A: This switch will fit anything. I mounted mine in the trunk by the battery and fuel pump wiring. Your vehicle should already have one from the factory. This is a safety switch to shut off the fuel pump in case of a collision.

### ⭐ Pinned Wrong
*by B***N on May 27, 2023*

The switch is wired to be normally open and not normally closed. The circuit is only closed when it is activated which is the opposite of what you want for power to a fuel pump. Repinning it is difficult. Also, the weather seals were not pushed in all the way and I had to seat them correctly.

### ⭐⭐⭐⭐ good switch easy to reconfigure
*by C***S on January 25, 2020*

Switch is easy to install. It comes NO and for my purposes needed to be NC. The change is not documented but easy to accomplish. If wiring change is necessary pry off the yellow cap on the plug (see picture) The wire positions are labeled COM NO and NC. It came configured with wires in the NO and COM. You will want to move the NO wire to the NC position. The wires are held in place with a retainer clip that can be pried back releasing the wire for easy removal, Insert a small screwdriver ( I used a 1.4 mm jewelers screwdriver) to release the wire. Look into the socket with a flashlight to determine the depth of the retainer and the direction that you need pry the retainer. It is easy to spot in the empty hole. A small flat screwdriver will work better than a round object like a paperclip. Pull on the wire that needs to be moved while prying the retainer, When released from the retainer pull the wire while prying the retainer and it will slide out of the hole. Move the wire to the desired location push it in from the rear of the socket engaging the retainer. Make sure the wire is centered in its location, replace the yellow cover plug in the wire socket and install the switch.
